CoolingJacket Advanced

CoolingJacket Advanced for thermal imagers

Our new CoolingJacket Advanced is the universal protection for your thermal imager from hot ambient temperatures. The cooling can be achieved by either water or air (cooling with air up to 100°C and with water up to 315 °C). It also allows the integration of additional components like PI NetBox, USB Server Gigabit and Industrial Process Interface (PIF) in the extended version. 

Ethernet Cat. 6, USB- and sensor cables for ambient temperatures up to 250 °C as well as an optional cable cooling for up to 315 °C are available.

Air purge for rugged environments

Air purge for rugged environments

The air purge unit complements the reliable CoolingJacket for use in harsh environments, especially in the metal and glass industries.

An integrated, infrared-transparent special window protects the optics of the camera or sensor on the one hand and enables an optimal laminar air flow on the other hand. This is particularly important because turbulence directly in front of the optics leads to dirt deposits. The Optris development engineers designed, extensively tested and optimized the air purge attachment in the in-house test center.

In harsh environments, the airflow in front of the CoolingJacket has proven to be as critical for reliable and accurate temperature measurements as the cooling itself. The air purge unit optimizes this airflow and allows both orthogonal (left) and parallel (right) airflow.

Outdoor protective housing

Outdoor protective housing for optris PI infrared cameras

The universal protection housing (IP 66) has been developed for outdoor operation of the optris PI infrared camera series. Through a built-in air purge collar, the IR cameras can be deployed in dusty and humid conditions for a continuous temperature monitoring. The possible inclusion of a USB Server Gigabit enables for an integration into process control systems over large distances via Ethernet.

Interchangeable lenses

Interchangeable lenses for optris PI thermal imagers

Interchangeable lenses are available for all optris PI infrared cameras. Additional lenses may also be purchased afterwards for every camera individually. The exact field of view at any measuring distance can be calculated for all lenses with our optics calculator.

Mechanical Accessories

Mechanical Accessories for thermal imagers

The infrared camera optris PI consists of a standard photo thread. It can be fitted directly or via an additional mounting base, adjustable in 2 axes.

Works Test Certificate

Works Test Certificate for infrared cameras

For each infrared camera we offer a works checking certificate against a small expense loading. The works checking certificate is sent out with your thermal imager.

Here you will find further information regarding the works test certificate.
